PUR (polyurethane) glue typically takes 24-48 hours to fully dry and cure. The exact drying time can vary depending on factors like:

Temperature and humidity - PUR glue dries faster in warmer, drier conditions.
Thickness of the glue line - Thicker applications will take longer to dry than thin, even layers.
Ventilation - Good air circulation helps the glue dry faster.
In general, you can expect PUR glue to feel dry to the touch within 1-2 hours, but it continues to cure and reach full strength over the next 24-48 hours. It's best to avoid putting too much stress on the joint until the glue has had time to fully cure.
